An approach to determine bandgap energy in graphene under shear strain condition

A simple analytical approach is presented to investigate the energy band structure of graphene under the application of shear strain. The strain-induced deformation in the unit cell in terms of the angle between two unit vectors is taken into consideration in the framework of nearest neighbor tight binding model. The proposed approach is applied to evaluate the energy band gap in graphene structure under shear strained condition. The results obtained from the proposed approach are compared with those of repo calculation and they are found to be in good agreement. This demonstrates that the proposed approach can be applied to calculate the band gap energy in shear strained graphene.
